摘要:
A process for processing a silver halide color photographic material is disclosed which comprises processing a silver halide color photographic material containing at least one compound represented by formula (I) or (II): ##STR1## wherein R.sub.1 and R.sub.2 each represents an aliphatic group, an aromatic group, or a heterocyclic group; A represents a group forming a chemical bond by reaction with an aromatic primary amine color developing agent; n represents 0 or 1; X represents a group released on reaction with an aromatic primary amine color developing agent; B represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, or a sulfonyl group; and Y represents a group accelerating the addition of an aromatic primary amine color developing agent to the compound of formula (II), and said R.sub.1 and X or said Y and R.sub.2 or B may combine with each other to form a ring, with a color developer prepared by diluting a concentrated color developer composition containing from 90 ml/liter to 600 ml/liter of benzyl alcohol and from 0.07 mol/liter to 0.5 mol/liter of an aromatic primary amine color developing agent.
